Nana Visitor appeared as four different characters in three episodes of Matlock: "The Best Friend" (1987), "The Other Woman" (1989), and "The Divorce" (1993). (In "The Other Woman," she had a dual role, playing both the wife and the mistress.)
The first of select Matlock episodes from around this time to resemble a movie plot. This one resembles The War of the Roses.
